Answer:
BC = 10cms
Step-by-step explanation:
Given,
AP= 4cm
AP=AR -------(tangents from the same point are equal)
therefore, AR=4cm
AC= AR+CR
11=4+CR
therefore, CR= 7cm
CR=CQ--------(tangents from the same point are equal)
therefore, CQ= 7cm
BP=BQ---------(tangents from the same point are equal)
BQ=3cm
BC=BQ+CQ
BC=3+7
therefore, BC=10cms
